CURT parts for the Infiniti FX45
Wiring, ball mount and the rest
A bike rack needs nothing but the hitch. A trailer needs lights, and the wiring guide walks you through four-flat and seven-way for the FX45.
Then a ball mount sized to the receiver: CURT 45836 ($41.70 CAD) drops straight into a 2-inch receiver. Pick the drop or rise that keeps the trailer level, and match the ball to the coupler. The ball mount guide covers both in two minutes.
Canadian winters eat hitch hardware. Salt and brine get into the receiver and the trailer plug, so a smear of grease on the pin, a cap on the receiver and a rinse under the bumper in spring keep a CURT hitch looking new for years. The rust and salt care guide has the full routine.
Infiniti FX45 hitch questions
Which CURT hitch fits my Infiniti FX45?
It depends on the year. CURT 13558 covers 2003 through 2007, a Class 3 hitch with a 2-inch receiver rated to 3,500 lb. Open your year page and the exact hitch, price and wiring are on it.
Can I put a bike rack on a FX45 with this hitch?
Yes. The 2-inch receiver takes any 2-inch rack, and a loaded rack counts against the hitch's tongue weight (350 lb on CURT 13558), so a four-bike platform rack with bikes on it is well inside the limit.
Can I install the hitch myself?
Most owners do. CURT rates CURT 13558 a novice install, about 45 minutes with hand tools and a jack. The install video above is the real job, uncut.
How much can a FX45 tow with a CURT hitch?
The hitch is rated to 3,500 lb, but the FX45's own tow rating in the owner's manual is the ceiling. The lower of the two numbers is your limit, every time.
